2. Style 1; petals strongly reflexed in anthesis so as to hide sepals, abaxially densely sericeous, long-fimbriate on the margin; 1 stamen much longer than the other 9; exotic from Asia escaped from cultivation in Florida.

3. Stipules borne on inner face of base of petiole, partially to completely connate in our species; shrubs or trees.

4. Leaves bearing glands on petiole or abaxial surface of lamina near base, and sometimes on adaxial surface near apex; some bracteoles often terminating in a large gland; styles of uniform thickness or widened at apex, the stigmas truncate or peltate; native in Cuba, probably introduced in the Lesser Antilles.

7. Petals usually described as lilac (or blue or purple), sometimes as pink, rarely as white; petioles eglandular or biglandular near apex, the glands usually not prominent; stipules if present borne on stem between petioles, distinct or connate in interpetiolar pairs.

11. Leaves usually bearing small marginal glands near base of lamina; pedicels raised on well-developed peduncles; exotic, widely cultivated as an ornamental shrub but apparently not becoming naturalized.

2. Styles 2 or 3; petals spreading to reflexed but not hiding sepals, abaxially glabrous or sparsely sericeous on abaxial midrib, entire, erose, or dentate on the margin; stamens without 1 much longer than all the others; native species.

12. Styles 2 or 3, distinct or partly to completely connate; apex of styles with stigmas terminal and without any sort of dorsal extension; carpels 2 or 3, developing into an indehiscent fleshy fruit; shrubs or trees.
